Dynamic Characteristics of Gravelly Soil Mixed with Different Fine Contents

For the purpose of investigating influence fine contents on dynamic properties mixed soil, a series triaxial tests were conducted gravelly soil with contents. The confining pressures 100, 150, and 200 kPa selected. carried out samples 0%, 20%, 40% respectively. axial strain pore water pressure curves specimens obtained when different excitation forces applied. experimental results indicated that strength soils presented an increasing tendency increase pressures. Under low pressure, increased at first then decreased contents, while appearing to downtrend under high pressure. When force was large, rapidly.
